A Node-RED node that runs an instance of the
rtl_433 tool. rtl_433 is a program to
decode traffic from devices that are broadcasting on 433.9 MHz, like temperature
sensors, door senors, tv remotes, garage door openers and such.
This is similiar to, and based on, the node-red-node-daemon that runs and monitors a long running system command.
This node calls out to the rtl_433 command at start time and then pipes all
the 433 MHz messages that are captured and decoded as valid JSON messages.
The goal is to reduce the effort needed to integrate the power of the rtl_433 tool into
nodeRED.
You will need a working version of the rtl_433 tool in your environment and validate it runs correctly. Those on Raspbian, Ubuntu, or Debian based systems should be safe to use the following helper script to do this work:
curl
https://raw.githubusercontent.com/dayne/node-red-contrib-rtl_433/master/install-rtl_433-app
| bash
After that completes and you reboot you should be able to run:
rtl_433 -F json
Success looks like the command running and capturing decoded messages from devices chirping.
recommended: Install the node via the NodeRED palette manager.
Local clone: If you want to hack on the code you can clone this repository locally and run the following command in your Node-RED user directory - typically
~/.node-red
Example:
cd ~/.node-red
npm i node-red-contrib-rtl_433
Install the node and then start writing flows. More examples later once folks contribute them.
This node is derived from the node-red-daemon node and focused on the specific command rtl_433 usage.
